The plot of the movie was imaginative- Dr Jekyll and Mr Hyde in reverse, gender as well as personality (Loretta is almost Mr Hyde while awake and Dr Jekyll in subconscious). Unlike what has been mentioned several times, (even by her screen father), it isn't sleep walking but schizophrenia and hence the plot is believable, including her failure to remember what her subconscious personality did, in detail. But she did remember, and tried to hint on screen, that she had been doing some thing naughty. The movie would have been excellent had a few gaps had been filled up and ironed out. She did knew her childhood sweetheart (John Raymond), but her reason of dislike isn't clear (which could have been clarified just in a few short dialogues, say with her colleague nurses). Quite a few other fillers would have made it into excellent movie. I give it above average in Plot, Loretta and Cotten - roles as well as execution, but that had been highly negated by the execution and also realization of both the doctor- who should have (and as it comes out did) guess but didn't take sufficient measures and more by her father, who obviously knew Raymond (he was the gardener of their family), as well as that the kids shared something sweet. He could have been a more pragmatic person say as the uncle in Katie Did It.
